NGC 322 is a lenticular galaxy located approximately 318 million light-years from the Solar System[2] in the constellation Phoenix. It was discovered on September 5, 1834 by John Herschel. It was described by Dreyer as "very faint, very small, round, a little brighter middle, 3 stars to west." It apparently seems to be interacting with PGC 95427, another galaxy.[3]

One supernova, SN 2018bwv (type Ia, mag. 16.2), was discovered in NGC 322 on 23 May, 2018.[4]

From legacy survey images a faint ring or tidal feature can be seen around NGC 322.[5]

An image processing of the DECam data that makes these faint features of the ring or tidal feature appear.
